Siss, LLC

Siss, LLC, a woman-owned small disadvantaged business based in Ephrata, Washington, operates as a prime contractor providing mobile water and sanitation infrastructure for federal emergency response and incident management, exclusively under small-business set-asides and full-and-open contracts with the U.S. Department of Agriculture Forest Service. The company supplies potable water trucks, gray water trucks, and trailer-mounted handwashing stations to support fire suppression, prescribed burns, and all-hazard incident response across western Forest Service regions.

Siss, LLC's customer base concentrates entirely within the Department of Agriculture's Forest Service ecosystem. The top five funding units account for 92% of recent awards by count and 97% by potential value, led by the Forest Service Fire and Aviation Management National Interagency Fire Center (6 awards, $2 million combined potential value), the R6 Pacific Northwest Region (14 awards, $468 thousand), and the R1 Northern Region (14 awards, $257 thousand), with secondary awards from the R2 Rocky Mountain Region and the Department of the Interior Bureau of Land Management Idaho Region. The split between volume and dollars reveals Siss's core positioning: the Interagency Fire Center anchors the largest contract vehicles (two $500,000 multiple-award IDIQs awarded February 6, 2026, and one $250,000 multiple-award IDIQ awarded May 28, 2024, all extending through May 2029), while regional offices drive high-frequency delivery-order activity against smaller set-aside vehicles. Recent representative work includes a $78,475 delivery order from Forest Service R2 for mobile water and sanitation services in Delta, Colorado (June 30, 2026); a $48,362.50 delivery order from R1 under the Virtual Incident Procurement (VIPR) system for operations in Kamiah, Idaho (August 31, 2025); and three small delivery orders totaling $37,740 from R1 in August 2026 for emergency support at Dalton Gardens, Idaho.

Siss holds seats on five named parent vehicles, all Forest Service or Interagency Fire Center IDIQs or blanket purchase agreements ranging from $85 thousand to $2 million in combined potential value per vehicle. The company operates entirely as a prime contractor (100% of awards); no subcontract work is reported. Work is categorized primarily under NAICS 238990 (Support Activities for Forestry) and PSC S206 (Natural Resources/Conservation—Forest-Range Fire Suppression/Presuppression). Activity has been episodic but recently accelerated: three awards in 2021, five in 2023, three in 2024, two in 2025, and seven in 2026 year-to-date. Combined potential value across the full portfolio stands at $2.9 million, with $597 thousand obligated (21% utilization). The company competes predominantly under total small-business set-asides, though several recent delivery orders carry no set-aside designation. Place of performance spans western Forest Service regions, including Idaho, Colorado, and Washington, with administrative oversight at the National Interagency Fire Center and regional Forest Service offices.
